(Variable name) is a Poison-type glitch move in Pokémon Red, Blue, and Yellow. It is capable of causing Super Glitch.
If this glitch move does not cause significant Super Glitch corruption (possible by having a 0x50 sub-tile early in the saved screen data) then it will function as a damaging move with no animation which restores half of the damage inflicted to the foe to the user as HP.
